Nursing license renewal looks simple from a distance — you renew on a date, you pay a fee, you attest to CE — but the cycle length is set by each state Board of Nursing independently and ranges from one year to three. The cycle anchor (the rule that decides when in that period your license actually expires) varies just as widely. For RNs and LPNs/LVNs working across multiple states, mismatched cycles are the single most common reason a license lapses on a date the nurse swore was a year away. Here is how the 2026 cycle map actually looks, what anchors each state uses, and where staggered RN/LPN schedules trip people up.
Biennial Is the Default — But "Biennial" Means Different Things
The majority of US Boards of Nursing run on a two-year renewal cycle for both RN and LPN/LVN licenses. Within that two-year norm, the anchor splits into three families:
- Birth-month anchor (most common): Texas (RN and LVN expire on the last day of the licensee's birth month every two years), Florida (RN and LPN, last day of birth month, biennial), Arizona (last day of birth month, biennial), Tennessee, Oklahoma, and most other birth-month states.
- Calendar-year anchor with fixed date: California (RN and LVN, last day of birth month, biennial — but the LVN runs on a different date scheme; see below), New York (RN and LPN, last day of birth month, every three years for NY actually — see triennial section), Illinois (RN and LPN, May 31 of even-numbered years for the universal renewal date).
- Even/odd birth-year anchor: Some states stagger renewals by birth year — licensees born in even years renew in even calendar years, odd years in odd. This keeps the BON workload distributed and is invisible until you try to predict your first renewal as a new endorsement licensee.
The takeaway: "biennial" tells you the duration but not the date. Always check the anchor rule on the specific state BON page before you mark a calendar.
Triennial States: Iowa and Washington
Two states run nursing licenses on a three-year cycle, and both use a birth-month anchor:
- Iowa: RN and LPN licenses expire on the 15th day of the licensee's birth month every three years. The renewal window opens on the 16th of the birth month in the year before expiration. First-time renewals are calculated as two years plus the months remaining to the next birth month, after which the standard 36-month cycle takes over.
- Washington: RN and LPN licenses renew on the licensee's birthday. Active practice nurses renew every three years; the cycle is anchored to the date of birth. CE for Washington is also tied to the three-year cycle, which means the per-cycle CE total is higher than in most biennial states even though the per-year load is similar.
Triennial states reduce the renewal frequency but extend the CE accumulation window — important when you are juggling multiple licenses on different cycles.
Annual States: Kentucky and Connecticut
A small group of states still runs nursing licenses on a one-year cycle:
- Kentucky: RN and LPN licenses renew annually. The renewal window opens September 15 and closes at midnight on October 31. CE accumulates on a parallel November 1 – October 31 window, so CE earned in the renewal-window months counts for the cycle just closing.
- Connecticut: RN and LPN renewals are annual and anchored to the licensee's date of birth. CT does not require formal CE for RN renewal at the state level, which softens the annual-cycle burden, but the renewal itself still happens every twelve months.
Annual cycles mean twelve-month CE planning windows and twelve-month fee outlays — small per renewal, but they add up across a multi-state portfolio.
Staggered RN and LPN Cycles in the Same State
A handful of states do not use the same cycle for RNs and LPNs, which catches dual-licensees and educators with both credentials:
- Georgia: Both RN and LPN licenses are biennial, but the LPN cycle is anchored to a different month set than the RN cycle. A nurse who upgrades from LPN to RN does not inherit the LPN expiration date — the new RN license starts a fresh biennial cycle from issuance.
- Missouri: RN licenses renew on April 30 of odd-numbered years; LPN licenses renew on May 31 of even-numbered years. A dual LPN/RN holder in Missouri has two different expiration months in different calendar years, which means CE planning has to satisfy both clocks independently.
If you hold both credentials in any state, never assume the cycles are coupled. Confirm each license's expiration date in Nursys or the state BON portal directly.
What This Means for CE Planning
Cycle length drives how you should batch CE:
- Biennial states: Most CE requirements are stated as a per-cycle total (e.g., 24 contact hours every two years). Front-load CE in year one if you also hold an annual-cycle license elsewhere — the same courses can usually be applied to both.
- Triennial states (IA, WA): CE totals are higher per cycle (often 36-45 hours), but the window is longer. Avoid the year-three rush; aim for one-third of the requirement per year.
- Annual states (KY, CT): Plan CE on a calendar-year basis. KY's November-to-October CE window is unusual — courses taken in November of the prior year count toward the cycle ending the next October.
- NLC compact-license holders: Your renewal cycle follows your primary state of residence only. A multistate license issued from Texas renews on the Texas biennial schedule even if you practice mostly in a triennial state.
How to Avoid a Lapse
Three habits prevent the most common lapses we see:
- Pull your expiration date from Nursys.com rather than memory or your physical license card. The license card sometimes displays the issuance date prominently and the expiration date in smaller print, leading to off-by-one-year mistakes.
- For multi-state nurses, build a single spreadsheet listing each state, license type, expiration date, cycle length, and CE due. Update it each time a license renews.
- Set calendar reminders 90 days, 30 days, and 7 days before each expiration. Most BONs open renewal 60-90 days early and impose late fees the day after expiration.
Lapsed nursing licenses can usually be reinstated, but reinstatement triggers fees, sometimes a CE audit, and in NLC states a temporary loss of multistate privilege. Our late-renewal guide covers the reinstatement mechanics in detail.

Renewal cycles are the foundation of nursing license maintenance, and they are the part most often gotten wrong by nurses, employers, and even credentialing teams. Get the cycle right, anchor your CE planning to it, and the rest of license maintenance becomes routine.
